(6) Install the drive pinion assembly and companion flange
with mating marks properly aligned, and tighten the
companion flange self-locking nut to the specified
torque by using the special tools.
(7) Measure the drive pinion turning torque (with oil seal) to verify that the drive pinion turning torque complies with
the standard value.
Standard value:
BearingBearingclassification lubrication Rotation torque
(starting friction torque)Nm (in.lbs.1
;;oy:;; (;5,,,,,, 1 ~%L; !
If there is a deviation from the standard value, check
whether or not there is incorrect tightening torque of
the companion flange tightening self-locking nut, or incorrect fitting of the oil seal.
. ADJUSTMENT OF DIFFERENTIAL GEAR BACKLASH Adjust the differential gear backlash by the followingprocedures:
(1) Assemble the side gears, side gear spacers, pinion gears, and pinion washers into the differential case.
(2) Temporarily install the pinion shaft.
NOTE
Do not drive in the lock pin yet.
(3) Adjust the differential gear backlash by the following procedures:
@ While locking the side gear with the wedge,
measure the differential gear backlash with a dial
indicator on the pinion gear.
NOTE
The measurement should be made for both pinion
gears individually.
Standard value:O-0.076 mm (O-.003 in.)
Limit:0.2 mm (.008 in.1

@ If the differential gear backlash exceeds the limit,
adjust the backlash by installing thicker side gear
spacers. @ Measure the differential gear backlash once again,
and confirm that it is within the limit.
NOTE
(1) After adjustment, check that the backlash is the
less than the limit and differential gear rotates
smoothly.
(2) When adjustment is impossible, replace the side
gear and the pinion gear as a set.

17. INSTALLATION OF DRIVE GEAR/18. SPRING PIN
(1) Before installing the drive gear, drive the spring pin into the differential case.
At this time, face the notch in the spring pin in the
direction shown in the figure and have it stick out from
the differential case by the dimension shown in the
figure.

(2)Use the special tool to press fit the drive gear until it hits
the end of the differential case.
At this time, the large chamfering of the inner cir-
cumference of the drive gear should be to the inside
(side touching the differential case).

24. INSTALLATION OF LOCK PIN
(1) Align the pinion shaft lock pin hole with the differential case lock pin hole, and drive in the lock pin.
(2) Stake the lock pin with a punch at two points.
25. INSTALLATION OF DRIVE GEAR
(1) Clean the drive gear attaching bolts.
(2) Use an
Ml0 X 1.25 tap to remove the adhesive
adhering to the threaded holes of the drive gear, and
then clean the threaded holes by applying compressed
air.
(3) Install the drive gear onto the differential case with the mating marks properly aligned. Tighten the bolts to the
specified torque in a diagonal sequence.

l ADJUSTMENT OF FINAL DRIVE GEAR BACKLASH
Adjust the final drive gear backlash by the followingprocedures:
(1) Install the side bearing spacers, which are thinner than those removed, to the side bearing outer races, and
then mount the differential case assembly into the gear
carrier.
NOTE
Select side bearing spacers with the same thickness for
both the drive pinion side and the drive gear side.
(2) Push the differential case to one side, and measure the clearance between the gear carrier and the side
bearing.
(3) Measure the thickness of the side bearing spacers on one side, select two pairs of spacers which correspond
to that thickness plus one half of the clearance plus0.05 mm I.002
in.), and then install one pair each to the
drive pinion side and the drive gear side.
(4) Install the side bearing spacers and differential case
, assembly, as shown in the illustration, to the gear
carrier.
